The R5900 CPU was removed some time ago (frankly I don't remember
why). This series add it back, but to prove it works, we also add
testing at the end.
The main motivation is to have MIPS R5900 coverage, but to be able
to run real world r5900 binaries, I had to implement more opcodes.
42 patches are a lot, but 3 are already queued in linux-user-for-6.0,
and the 11 last ones are pure testing. I suppose in next versions
I'll split the testing patches, but to show the final objective I
included them in here.
I tagged it RFC because some parts because:
- We'd rather not add yet another target, but we need the
ILP32-on-64bit ABI (o32 64-bit)
- RDHWR glibc kludge for user-mode
- Avocado patches are only here to show the final test.
They are useful for my set of tests, but not meant to
be merged in mainstream.
- gitlab jobs are only here to show the tests work.
If the target is ever accepted, it would go in an already
existing job.
I'm OK to maintain 64-bit o32 and the testing out of tree, but the
TCG opcodes are worthwhile review for mainstream.
Note: there is a sign-extension bug somewhere but I can't find it:
